According to ESRB, this game contains: Blood and Gore, Violence
Parents, there is plenty of lifelike violence in Ghost Recon, but it's not graphic or gratuitous. It is a military sim with some complex themes that may not be suitable for youngsters.
Clancy fans, whether fans of his books or games, will find all the action and cold-war-esque themes that one would expect. The detail and realism is there as well, though not as predominate as in the Rainbow Six games.
PC and Xbox Live owners should not hesitate to take it online. Sorry Playstation 2 owners, there's no online play, but it is still has strong single and multiplayer options.
Deaf and Hard of Hearing gamers should note that the game does rely heavily on audio cues, and of course Xbox Live requires voice communication for an optimal experience.
